To all 'whom t may concern:

Be it known -that I, FRANK B. DE Morra,- a citizen of the United States' residing at Warrensburg', in thelcounty of Macon and State of Illinois, have invented certain new and useful VImprovements, in Cans; and I' terior of a can whereby when the canlis' subjected to the sterilizing rocess the heat will be conducted from the ody of the can to and through the center or middleof the bulk of the contents being treated, greatly reducing the time necessar to sterilize, the

flavor of thefinished s being thereby better than when long processing is neces# sary as when the ordinary form of can is Another object is to construct-,a canA of the type named havin a conductor of heat incorporated in its ma e-u and that forms ducted A,through the contents of the can, whereby togreatl shorten the time usually necessary to ,.-steri ize agiven bulkof ma- T'Still another object of the invention is tof construct a tubular conductor of heat open# ing at one end throu h'the body'of the can. and extending into t e interior of the can.

by which the heating medium may .in' troduced into the center of 'the bulk of the materials vunder treatment.

in the Present day methodof steriiizing time required is found to be detrimental to the flavor of the goods under. treatinentrv That is to say, every minute of time that the goods are subjected to heat beyond a certain point tends to aect the avor to its disadvantage. Therefore, structure will admit of a comparatively short steril-izing time, but one sufficient to destroy the bacteria of the particular product under treatment, means a far better flavor, which must reect upon the cost of Asary va can or in Imakin of Fig. 1, in erspective.

Fg. 6 is a longitudinal" section of .the

same.

In Fig.' 1

Athe can is represented by the process carried lout in any of the approved :ways-one of'fwhich is that of placing the f a part of the can, sovthat eat willl be confilled cans in a `steam ,retort where,th eyl are thc center ofthe can reaches 'a oint where all' bacteria will be destroy Corn of about. minutes a temperature ofi 250 degrees to complete sterilii'iation,- other classes of goods varying in the time required for their treatment.

As stated earlier herein, the subjection of vgoods is retained in aina'rkeddegree.v

The use of a conductor for heat extend-I 'kept until the temperature ofthe goods at ,to `average ct'msistenoggV for example,` requires thel goods to thistreatment 'for too long'a I; vtini'e detractsfrom the fiavor thereof'where- 'l' j -as-when treated for a much less time exv` v pe'ri'ence has shown that the davor of theloo4 n or like means. It consists, in the present instance', of two pieces of metal 2, 3, each of a width.v to fit snugly in the can 'against its side walls, Figure 1, each piece being slit midway its width for about. one-half its length'as 4,15 toperlnit them'to slide. upon Y one another"formin one. of their ends t pieces are. preferably recessed at 6 whereby as they restrupon one of the end walls of thecan 1 the contents of said can may readily circulate,` and at their.
